Hi,
I can install and customize accounting module as per the Spanish catalog. I have done similar for India, UAE and New Zealand accounting rules as per the client's requirement. I won't be able to share you that as it was developed under NDA. Customization was mostly done on payment methods, required custom fields additions, Invoice report customization, payment entries, develop and customized module as per modified rules in GST etc.
Besides, I have also custom work on Sales, Inventory, POS, HR, Purchase, Production, Procurement, Manufacturing, eCommerce related modules like odoo_size_chart, request_quote, product_bundle_plus, prod_exp_date_warn, productgiftwrap etc.
I am pretty sure I can do this custom job with quality work.
Looking forward to work with you.
Thanks in advance.
Shweta
